What symptom does anal canal rectum cancer have?

The etiology and pathology are mainly due to melancholy, seven emotions internal injury, resulting in blockage of meridians, qi stagnation and blood stasis, symptoms of anal rectal cancer, or due to unclean diet, excessive eating, hot and humid; Or due to chronic diarrhea and dysentery, the spleen is not healthy and the phlegm dampness is endogenous; Or because of exogenous six Yin, dampness and heat toxin accumulation.

matters needing attention

If there is a lack of fiber in the diet, the feces in the colon will become dry and hard. In addition, the speed of passage is slow, and the abdominal wall muscles become weak, so that the emptying time is prolonged. If the time is too long, the risk of rectal cancer will be relatively increased. Many studies have confirmed that the fiber in food can dilute the carcinogenic substances in oil, and also accelerate the speed of carcinogenic substances excreted through the digestive system.
